While my decision hasn't been sent yet (or it has and its just going through the mail), I do want to plan ahead for college, since I haven't lived at a dorm before and I would be living for the most part on my own from January on.

So, my question to everyone here is, what should I do? What are the must haves for living on campus? What neat tricks helped you save money or made things easier for you? What are the dos and the do nots?
